Abstract (en)
Axial magnetic bearings are described suitable for use where high loads and high rotational speeds are found together. In an axial magnetic bearing, for thrusts along the shaft (31) in one direction, there are included, in relation to the shaft (31), a generally radially extending thrust accepting face (38,43); and an electromagnet (37), with a face of each pole (36) thereof parallel to, but spaced from, an individually associated portion of the thrust face (38,43). The rotor disc (32) is tapered in the radially outward direction, to reduce the mass of the disc (32). Thus, the two said portions of the thrust face (38,43) are radially separated, and are separated from each other along the axis of the shaft (31). Possibly, the two said portions of the thrust face (38,43) extend precisely radially, between the portions there being a part of the thrust face (38,43) in the shape of a truncated cone.
